+
+## Java GUI
+
+### GUI Basics
+- [Lecture Notes](lecture-notes/GUI_Basics.ppt)
+
+- [Swing Notes](lecture-notes/Creating_User_Interfaces_Swing.ppt)
+
+- Swing (interface) vs. AWT (event handling)
+
+-	```java
+	import javax.swing.*;
+	
+	public class MyFrame {
+		public static void main(String[] args) {
+			JFrame frame = new JFrame("Test Frame");
+			frame.setSize(400, 300);
+			frame.setLocationRelativeTo(null);
+			frame.setVisible(true);
+			frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
+		}
+	}
+	```
+
+- 	```java
+	import javax.swing.*;
+
+	public class MyFrameWithComponents { 
+		public static void main(String[] args) { 
+			JFrame frame = new JFrame( "MyFrameWithComponen")
+
+			JButton jbtOK = new JButton("OK"); // Add a button into the frame 
+			frame.add(jbtOK); 
+
+			frame.setSize(400, 300); 
+			frame.setDefau1tC10seOperation(JFrame.EXIT_ON_CLOSE); 
+			frame.setLocationRe1ativeTo(nu11); // Center the frame 
+			frame.setVisib1e(true);
+		}
+	}
+	```
+- [JFrame with inheritence](programs/MyFrame1.java)
+
+### Layout Manager
+- For arraning a position into containers
+
+- [FlowLayout](programs/ShowFlowLayout.java)
+
+- [GridLayout](programs/ShowGridLayout.java)
+
+- [BorderLayout](programs/ShowBorderLayout.java)
+
+- `Color` class
+	- ```java
+	  Color mycolor = new Color(228, 100, 50);
+	  // how to set for button
+	  mybutton.setBackground(Color.mycolor);
+	  mybutton.setForeground(Color.mycolor);
+	  ```
+
+### JPanel
+- In `JFrame` we add a component `JPanel`
+
+- [TestPanels](programs/TestPanels.java)
+
+### Event-Handling in Java (Event-Driven Programming)
+
+- [Lecture Notes](lecture-notes/Event-Driven_Programming.ppt)
+
+- Event-driven programming (depends of action) <-> procedural programming (step by step)
+
+- [HandleEvent](programs/HandleEvent.java)
+
+- [HandleEvent1](programs/HandleEvent1.java) with the use of Inner Classes
+
+-	```
+	User Action						Object			Generated
+
+	Click a button					JButton			ActionEvent
+	Click a check box				JCheckBox		ItemEvent, ActionEvent
+	Click a radio button			JRadioButton	ItemEvent, ActionEvent
+	Press return on a text field	JTextField		ActionEvent
+	Select a new item				JComboBox		ItemEvent, ActionEvent
+	Window opened, closed, etc.		Window			WindowEvent 
+	Mouse pressed, released, etc.	Component		MouseEvent 
+	Key released, pressed, etc. 	Component		KeyEvent 
+	```
+
+-	```
+	Event Class		Listener Interface	Listener Methods (Handlers)
+	ActionEvent		ActionListener		actionPerformed(ActionEvent)
+	ItemEvent		ItemListener		itemStateChanged(ItemEvent)
+	WindowEvent		WindowListener		windowClosing(WindowEvent)
+										windowOpened(WindowEvent)
+										windowIconified(WindowEvent)
+										windowDeiconified(WindowEvent)
+										windowClosed(WindowEvent)
+										windowActivated(WindowEvent)
+										windowDeactivated(WindowEvent)
+	ContainerEvent	ContainerListener	componentAdded(ContainerEvent)
+										componentRemoved(ContainerEvent) 
+	MouseEvent		MouseListener		mousePressed(MouseEvent)
+										mouseReleased(MouseEvent) 
+										mouseClicked(MouseEvent)
+										mouseExited(MouseEvent)	
+										mouseEntered(MouseEvent)
+	KeyEvent		KeyListener			keyPressed(KeyEvent)
+										keyReleased(KeyEvent) 
+										keyTypeed(KeyEvent)
